New Features on Bitcoin Core v0.12.1rc2
Reddit user Keystrike abundant the changes fabricated from the antecedent version:
“First adaptation $.25 BIP9 softfork deployment
“This absolution includes a bendable angle deployment to accomplish BIP68, BIP112and [BIP113][] application the BIP9deployment mechanism.
“The deployment sets the block adaptation cardinal to 0x20250001 amid midnight 1st May 2025 and midnight 1st May 2025 to arresting address for deployment. The adaptation cardinal consists of 0x20250000 to announce adaptation $.25 calm with ambience bit 0 to announce abutment for this accumulated deployment, apparent as “csv” in the getblockchaininfo RPC call.
“For added advice about the bendable bifurcation change, amuse see https://github.com/bitcoin/bitcoin/pull/7648
“This specific backport pull-request can be beheld at https://github.com/bitcoin/bitcoin/pull/7543
“BIP68introduces about lock-time consensus-enforced semantics of the arrangement cardinal acreage to accredit a active transaction ascribe to abide invalid for a authentic aeon of time afterwards acceptance of its agnate outpoint.
“For added advice about the implementation, see https://github.com/bitcoin/bitcoin/pull/7184
“BIP112redefines the absolute OP_NOP3 as OP_CHECKSEQUENCEVERIFY (CSV) for a new opcode in the Bitcoin scripting arrangement that in aggregate with BIP68allows beheading pathways of a calligraphy to be belted based on the age of the achievement actuality spent.
“For added advice about the implementation, see https://github.com/bitcoin/bitcoin/pull/7524
“Bitcoin Core 0.11.2 ahead alien mempool-only locktime administration application GetMedianTimePast(). This absolution seeks to accord accomplish the rule.
“Bitcoin affairs currently may specify a locktime advertence back they may be added to a accurate block. Current accord rules crave that blocks accept a block attack time greater than the locktime defined in any transaction in that block.
“Miners get to acquire what time they use for their attack time, with the accord aphorism actuality that no bulge will acquire a block whose time is added than two hours in the future. This creates a allurement for miners to set their attack times to approaching ethics in adjustment to accommodate locktimed affairs which weren’t declared to be included for up to two added hours.
“The accord rules additionally specify that accurate blocks may accept a attack time greater than that of the average of the 11 antecedent blocks. This GetMedianTimePast() time has a key affection we about accessory with time: it can’t go backwards.
“[BIP113][] specifies a bendable angle activated in this absolution that weakens this abnormal allurement for alone miners to use a approaching time by acute that accurate blocks accept a computed GetMedianTimePast() greater than the locktime defined in any transaction in that block.
“Mempool admittance rules currently crave affairs to be accurate for actual admittance in a block in adjustment to be accustomed into the mempool. This absolution begins applying the BIP113 aphorism to accustomed transactions, so transaction whose time is greater than the GetMedianTimePast() will no best be accustomed into the mempool.
“Implication for miners: you will activate abnegation affairs that would not be accurate beneath BIP113, which will anticipate you from bearing invalid blocks back BIP113 is activated on the network. Any affairs which are accurate beneath the accepted rules but not yet accurate beneath the BIP113 rules will either be mined by added miners or delayed until they are accurate beneath BIP113. Note, however, that time-based locktime affairs are added or beneath concealed on the arrangement currently.
“Implication for users: GetMedianTimePast() consistently trails abaft the accepted time, so a transaction locktime set to the present time will be alone by nodes active this absolution until the average time moves forward. To compensate, decrease one hour (3,600 seconds) from your locktimes to acquiesce those affairs to be included in mempools at about the accepted time.
“For added advice about the implementation, see https://github.com/bitcoin/bitcoin/pull/6566
“The p2p active arrangement is off by default. To about-face on, use -alert with startup configuration.”
